Vocabulary develops at an early age. Infants begin learning language through sounds to employ them later when forming their first words. Young children use vocabulary to communicate basic needs and desires, and only later will it be used to communicate abstract ideas and concepts. The process of understanding a language thus begins with the bare essentials. In coming to understand and use vocabulary, the way the words are structured will become more evident. As more words are added to one’s vocabulary, the way the words operate with one another becomes critical. From this usage of vocabulary, a grammar develops.
